Searching for the Maven executable in a portable way.

[khmarbaise]

Currently I'm using the following code

    String mavenHome = System.getProperty("maven.home");
    if (mavenHome == null || mavenHome.isEmpty()) {
      //FIXME: currently not set; using hard coded path? Need to reconsider how to set it?
      mavenHome = "/Users/khmarbaise/tools/maven";
    }
    String mvnLocation = mavenHome + "/bin/mvn";
    if (OS.WINDOWS.isCurrentOs()) {
      mvnLocation += ".cmd";
    }

The obvious thing here is of course that I use a hard coded path of my own machine which has to be removed and replaced with a search via PATH. Furthermore the mvnLocation should be checked via the PATH.
